can someone verify what manual I need please

[starsh1p]

The seriel number on my engine is B403574, the engine is a gm 4 cylinder 140. i believe I should be using manual # 10, am I correct. The models covered section seem to verify this but I just wanted to check with you pros . Thanks

#10 lists 85-89 ,120-140
You downloading it?

not downloading it, I already have them all. Just wanted to be sure I was using the correct one. At first I thought it was #3 but after i checked the models covered section I went with #10, just wanted to be sure. Thanks for the reply

Pretty sure my engine is an 84 but the seriel number points me to #10 so ....must be an 85 lol

Nope your engine is a 1986 MERCRUISER 140, And service manual number 10 is correct.
